From 0d34282fdde1d8f337d2a9e10f5ac793b12ef2e7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Mon, 17 Dec 2012 07:12:13 +0100 Subject: [PATCH] cpu: Move host_tid field to CPUState MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Change gdbstub's cpu_index() argument to CPUState now that CPUArchState is no longer used.
